is Sunday in Mid-Lent, a great holiday, when the Pope blesses the golden rose, and children go home to their mothers to feast on mothering cakes. It is said that the day received its appellation from the ancient custom of visiting their mother church, and making offerings on the altar on that day. Used by school-children it means a holiday, when they went home to spend the day with their mother or parents.
